Description

Self-cleaning air conditioner filter assembly, air conditioner

technical field

The invention relates to the technical field of air conditioners, in particular to an automatically cleanable air conditioner filter screen assembly and an air conditioner.

Background technique

As a device for adjusting indoor air temperature and humidity, air conditioners have brought great convenience to people. With the improvement of people's quality of life, the utilization rate of air conditioners is also increasing, especially in summer, air conditioners are essential of. The air conditioner includes an indoor unit and an outdoor unit. When cooling, the heat exchange device in the indoor unit acts as an evaporator, and the heat exchange device in the outdoor unit acts as a condenser. When the refrigerant flows into the evaporator, it absorbs the heat in the room through evaporation and flows to the outside. The advanced condenser condenses and dissipates heat to cool down, and this cycle realizes the cooling of the indoor air. When heating, the refrigerant flows in the opposite direction to heat the indoor air.

In the current wall-mounted air conditioners, air filters are generally installed to filter the air passing through them to improve indoor air quality. However, after long-term use, a lot of dust and dirt will adhere to the air filters, which will cause The air blown out from the air outlet of the air conditioner has a peculiar smell, even a musty smell, which seriously affects the comfort of the user.

Of course, the air filter in the current air conditioner can be removed and cleaned manually, but in actual use, few users will remove the air filter for cleaning by themselves. After a long time of use, the air conditioner becomes air Pollution sources, especially in some cities with poor air quality, when the doors and windows are opened, the bad outdoor air will enter the room, making the indoor air conditioner filter work harder. Therefore, let the air conditioner have the ability to automatically clean the air conditioner filter The function is very necessary. There is also an air conditioner that can automatically clean the air filter. It uses a circulating air filter. After the air filter is dirty, the motor drives the filter to rotate circularly. There is a cleaning water tank on the circulation path. Clean the dirty air filter, but this method is not suitable for the wall-mounted air conditioner, the internal layout of the wall-mounted air conditioner is compact, and there are many internal charged components, this structure will make the components get dirty by the water in the water tank If it is wet, there will be abnormalities, and there is even a risk of electric shock, and when it is used for a long time, a lot of dirt will remain in the water tank, which will also cause secondary pollution to the filter. Therefore, this kind of water tank also needs to be removed regularly and cleaned manually. It has caused a lot of inconvenience to users, so a wall-mounted air conditioner that can truly fully automatically clean the air filter is necessary.
